CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2020/3377 filed on Jan. 13, 2021, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. This application is also co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program from the same parentage that is entitled Buddleja Plant Named ‘Botex 002’ (U.S. Plant patent application Ser. No. 17/556,977).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Buddleja davidii will be referred to hereafter by its cultivar name, ‘Botex 001’. ‘Botex 001’ is a new shrub grown for use as an ornamental landscape plant.

The new cultivar of Buddleja is a selection from an ongoing breeding program conducted by the Inventor in Kaatsheuvel, The Netherlands with the objective of creating new cultivars of Buddleja with very neat and compact plant habits combined with unique flower colors and floriferous blooming habits.

The Inventor made a cross in summer of 2018 between an unnamed and unpatented proprietary plants in the Inventor's breeding program; reference no. 11010 as the female parent and reference no. 263 as the male parent. The Inventor selected ‘Botex 001’ in summer of 2019 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by the Inventor using stem cuttings in Kaatsheuvel, The Netherlands in August of 2019. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Botex 001’ as a unique cultivar of Buddleja.

-   1. ‘Botex 001’ exhibits a very compact, dense, and upright-rounded     plant habit. -   2. ‘Botex 001’ exhibits flowers that are intense purple in color. -   3. ‘Botex 001’ exhibits a very floriferous blooming habit. -   4. ‘Botex 001’ exhibits flowers that have a pleasant fragrance.

The female parent of ‘Botex 001’ differs from ‘Botex 001’ in having inflorescences that are shorter in length with flowers that are lighter purple in color and in having a less upright and more spreading plant habit. The male parent of ‘Botex 001’ differs from ‘Botex 001’ in having inflorescences that are smaller in size and less dense with flower centers that are purple in color and in having a less upright and more spreading plant habit. ‘Botex 001’ can also be compared to the Buddleja cultivars ‘Nanho Purple’ (not patented) and ‘BotEx 002’. ‘Nanho Purple’ differs from ‘Botex 001’ in having a taller plant height and spreading plant habit with arching branches. ‘Botex 002’ differs from ‘Botex 001’ in having a more spreading plant habit and flowers that are lighter and more lilac in color.
